During the installation a <br /> full-port ball valve should be installed at the base of any vertical discharge_pipe work form the unit to allow easy <br /> service of the unit. <br /> 3-8-6 . GRAVITY FALL: <br /> The unit accepts wastewater by gravity; it does not"vacuum"in water.All inlet pipe work must have a positive gravity <br /> fall(114"per foot minimum).All horizontal piping from the macerating unit must also have a positive gravity fall to <br /> allow free drainage when the pump stops. <br /> 3-8-7 THREE FEET MINIMUM <br /> The macerating unit must be at least 3 feet from the soil stack.This will allow the macerator to operate for an <br /> adequate period of time to ensure efficient waste reduction. <br /> 3-8-8 SOIL STACK CONNECTION <br /> All discharge pipe work must be connected to the soil stack by an appropriate and approved connection.A"tee"or"y" <br /> fitting as shown is preferable. <br /> 3-8-9 NO DIAGONAL"UPHILL" PIPE RUNS <br /> All discharge pipe work from the unit should run either directly vertical or in a horizontal plane(with a minimum%"per <br /> foot)to the point of discharge. Pipe work should not be installed with a diagonal upward slope from the unit to the <br /> point of discharge. <br /> 3-8-10 PIPE WORK <br /> All pipe work should be copper, PVC,or CPVC. Do not use flexible piping. Hangers should not be less than 4 feet <br /> apart to prevent pipe rattling. <br /> 3-8-11 FLUSHING <br /> Macerating systems requires a minimum of 1.6 gallons of water to operate satisfactorily. <br /> 3-8-12 DISCHARGE <br /> Never discharge directly into an open drain,fixture,manhole or rainwater drainpipe. It is illegal for it constitutes a <br /> health hazard. Direct connections into sanitary waste systems only shall be acceptable. <br /> 3-8-13 FREEZING <br /> Ensure all pipe work susceptible to freezing is adequately insulated or heated. In unheated buildings,the toilet, piping <br /> and macerating unit must be properly winterized. Use plumbers'anti-freeze or drain completely. <br /> i <br /> 3-8-14 ELECTRICITY <br /> Before attempting any maintenance or servicing,the unit must be disconnected from the power source.The <br /> macerating system must be connected to a Ground Fault Circuit Interrupter(GFCi). <br /> QCopyright 2008 Liberty Pumps Inc.
